According to SM Entertainment, the duo's new mini album 'Goody Bag' will contain a total of 6 tracks - all composed by Jungmo and lyrics written by Heechul - including their trot title track, "Ulsanbawi"!

We can't wait to see how rock and trot come together for M&D's new title song! 'Goody Bag' is set for release July 12.

I can't wait for them to return. It's so refreshing to see a group that composed, writes, and produces their own music. It gives their songs an authentic and genuine feel. Jungmo's composition skills are amazing, and HEECHUL lyrics are alway so complex and beautiful. Plus, Heechul's voice was made for trot and rock, so the combo will be perfect, even if it sounds strange.
